Question

3.The ratio of time period of a particle to that of proton circulating with same speed in the same unit
magnetic field is
(a) V2:1
(b) :v
(c) 1:2
(d) 2:1
how? ​

Answer 1

Answer:

this answer is V2:1.…...

Answer 2

Answer: D

Explanation:

                        T$\alpha$ = 2$\pi$m/qB

                              = 2$\pi$*4m(mass of alpha particle)/2e *q

             T(proton) = 2$\pi$m'/q'B

                               =2$\pi$*m'/e*B

               

                     R$\alpha$/Rp = 2$\pi$4m/2e*B * e*b/2$\pi$*m'

                      R$\alpha$/Rp = 2/1

                                  = 2:1
